Brief Summary
This study assesses computed tomography (CT) perfusion imaging in predicting treatment response in patients with non-small cell lung cancer or tumors that have spread from the primary site (place where it started) to the lungs (metastases) treated with stereotactic ablative radiation therapy. CT perfusion imaging is a special type of CT that uses an injected dye in order to see how blood flow through tissues, including lung tissue. CT perfusion imaging of the lungs may help doctors learn whether perfusion characteristics of lung tumors may be predictive of response to treatment and whether lung perfusion characteristics can be used to follow response to treatment.

Outcome Measures
Primary Outcomes (3)
Number of participants able to complete perfusion scan acquisition at the time of treatment-planning
Up to approximately 90 seconds
Number of participants able to complete perfusion scan acquisition within 48 hours of SABR
Within 48 hours post-SABR
Number of participants able to complete perfusion scan acquisition in follow-up up to 4 months after SABR
Up to 4 months post-SABR
Secondary Outcomes (4)
The calculated variance of blood flow such that measurable changes can be identified in future studies
Baseline to up to 4 months post-SABR
The calculated variance of blood volume such that measurable changes can be identified in future studies
Baseline to up to 4 months post-SABR
The calculated variance of mean transit time such that measurable changes can be identified in future studies
Baseline to up to 4 months post-SABR
The calculated variance of permeability such that measurable changes can be identified in future studies
Baseline to up to 4 months post-SABR
Study Arms (1)
Diagnostic (CT perfusion imaging)
EXPERIMENTALPatients undergo CT perfusion imaging of the lungs at baseline, within 48 hours of first SABR, and at 2-4 months after completion of SABR. Isovue-200 is used as contrast agent
Interventions
Cancer Personalized Profiling by Deep Sequencing (CAPP-Seq) is an assay which allows quantitative assessment of the levels of circulating-tumor DNA in the blood sample.
Eligibility Criteria
You may qualify if:
- Patients undergoing SABR for the treatment of a lung tumor, inclusive of non-small cell lung cancer or lung metastases
You may not qualify if:
- Patients who are pregnant or are trying to become pregnant are excluded from this study
- Patients with renal failure, defined as glomerular filtration rate (GFR) \< 60 at the time of the radiation treatment-planning (RTP) scan, will be excluded
